How do wells and boreholes shape settlement patterns in the Kalahari?

In the Kalahari Desert, water availability is the primary limiting factor for human habitation. Because surface water is largely nonexistent across much of the region—with rain typically disappearing into deep sand or evaporating—settlement patterns are strictly confined to locations situated near wells or boreholes that provide access to potable water.12

These water sources are essential for supporting the region's cattle-based economy. Because year-round grazing is restricted to the vicinity of these wells and boreholes, they serve as the focal points for village life. While pastoralists may occasionally trek to remote pastures during periods of above-average rainfall, the reliance on permanent water infrastructure remains the defining constraint on where people can establish stable, long-term settlements.1
